Yang Tian refined the souls and lives of the Four Great Demon Kings: Mouse Spirit, Centipede Spirit, and Poisonous Snake Spirit into four Demon Talismans.
He attached them to Guo Jing, Wu Yue, Liu Shi, and Wang Ying.
This way, they can be protected.
These Demon Talismans are refined from four demons of the Demon King level, with immense power.
Even if Hua Wuqing personally took action, she wouldn't be able to kill Guo Jing, Wu Yue, Liu Shi, and Wang Ying quickly.
After all, the power of the four Demon Kings is equivalent to the existence of Half-Immortal Realm in the Human Realm.
After doing all this, Yang Tian drew the Holy Sword, bit his finger, and let a drop of fresh blood out.
He drew lines of blood spells on the Holy Sword.
"Sword Soul, I have released the soul contract between us. From now on, you are no longer my servant!"
Yang Tian took a sip of blood and spat it onto the Holy Sword.
The originally pure white Holy Sword turned blood-red at that moment.
